What to do with important data in a timely manner to prevent data loss due to unexpected situations

If your system's hardware or storage media fails, the Backup tool can help you protect your data from unexpected loss.

#For example, you can use Backup to create a copy of the data on your hard drive and then store the data to another storage device. (Recommended learning: web front-end video tutorial)

The backup storage media can be either a logical drive (such as a hard disk), an independent storage device (such as a removable disk), or an automatic Converters organize and control an entire disk library or tape library.

If the original data on the hard drive is accidentally deleted or overwritten, or the data is inaccessible due to hard drive failure, you can easily restore the data from the archive copy.

Backup: To cope with possible unexpected situations such as loss or damage of files and data, copy the data in the electronic computer storage device to a large-capacity storage device such as tape.

So that a copy of the program or file can be stored independently from the original text. (Excerpted from "Computer Science")

Backup can be divided into system backup and data backup.

1. System backup: refers to the loss of system files of the user's operating system due to disk damage or damage, computer viruses or human error deletion, etc., resulting in the computer operating system not being able to boot normally. Therefore Use system backup to store the operating system in advance for backup support after a failure.

2. Data backup: refers to the user storing data including files, databases, applications, etc. for use in data recovery.

The backup is used for backup support and replacement.

Backup is the basis of disaster recovery. It refers to the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by operating errors or system failures. .

Traditional data backup mainly uses built-in or external tape drives for cold backup. However, this method can only prevent human faults such as operational errors, and the recovery time is also very long.

With the continuous development of technology and the massive increase in data, many companies have begun to adopt network backup. Network backup is generally implemented through professional data storage management software combined with corresponding hardware and storage devices.
